But will there be a hard fork?
We will see... But we are talking of roughly 500,000 ETH which sure makes a lot of money but isn't in any way comparable to the 11,500,000 ETH that the DAO used to hold back in the day (among which 3,600,000 ETH were stolen by the hacker). That's partly why you'll see that the hard fork isn't the solution
which has the more upvotes on the Reddit thread.
IMHO, it's Parity's problem to handle and a good lesson for the next future. But there is also an interesting idea to implement an old EIP (suggested after the DAO mess) making contracts somehow fault-tolerant: read more about it
